   How does health monitoring affect intelligent load balancing decisions?

   • AIt increases the weight of servers that respond quickly to health checks
   • BIt excludes unhealthy servers from the pool, so traffic is only sent to servers that pass health checks
   • CIt causes the load balancer to send more traffic to servers that fail health checks
   • DIt has no effect on load balancing decisions

   A company runs a long-lived WebSocket application where clients maintain connections for hours. The pool has three servers. The administrator notices that one server is handling significantly more active connections than the others, even though the load balancing method is Round Robin. What is the most likely explanation?

   • AThe virtual server is configured with a persistence profile that is overriding the load balancing method.
   • BThe load balancing method is actually Least Connections, not Round Robin.
   • CRound Robin distributes new connections evenly, but it does not account for the duration of existing connections, so servers with longer-lived connections accumulate more active sessions.
   • DThe health monitor is marking the other servers down intermittently.

   A pool of three web servers is configured with the Least Connections load balancing method. One server has been failing its HTTP health check for the past 10 minutes. What will the BIG-IP do with new connections destined for this pool?

   • ASend new connections only to the two healthy servers, excluding the failed server from selection.
   • BSend new connections to the failed server only if it has the fewest connections.
   • CSend new connections to the failed server and generate an alert to the administrator.
   • DContinue to send new connections to the failed server because Least Connections does not use health checks.
